Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Table names must follow the rules for identifiers. Creates the new table as a FileTable. You do not specify columns because a FileTable has a fixed schema.
For more information, see FileTables. The column is computed from an expression that uses other columns in the same table. The expression can be a noncomputed column name, constant, function, variable, and any combination of these connected by one or more operators. The expression cannot be a subquery or contain alias data types. Each row in a table can have different values for columns that are involved in a computed column; therefore, the computed column may not have the same value for each row.
Based on the expressions that are used, the nullability of computed columns is determined automatically by the Database Engine.
The result of most expressions is considered nullable even if only nonnullable columns are present, because possible underflows or overflows also produce Microsoft sql server standard 2014 free results. Помощь vmware workstation 14 slow free more information, see Indexes on Computed Columns.
If filegroup is specified, the table is stored in the named filegroup. The filegroup must exist within the database.
If "default" is specified, or if ON is not specified at all, the table is stored on the default filegroup. These constraints create indexes.
If filegroup is specified, the index is stored in the named filegroup. If "default" is specified, or if ON is not specified at all, the index is stored in the same filegroup as the table. In this context, default is not a keyword. It is an identifier for the default filegroup and must be delimited, as in ON "default" or ON [ default ]. This microsoft sql server standard 2014 free the default setting.
This can improve concurrency by enabling locks to escalate to partition HoBT level instead of the table. Varchar maxnvarchar maxvarbinary maxxml and large UDT values are stored directly in the data row, up to a limit of 8, bytes and as long as the value can fit the нажмите для деталей. If /50721.txt value does not fit in the record, a pointer is stored microsoft sql server standard 2014 free and the rest is stored out of row in the LOB storage space.
This partition microsoft sql server standard 2014 free must use the same partition function and partition columns as the microsoft sql server standard 2014 free scheme for the table; otherwise, an error is raised.
For disk-based tables, the data type can be one of the following:. For more information about valid precision values, see Precision, Scale, and Length. For more information about valid scale values, see Precision, Scale, and Length. Only a constant value, such as microsoft sql server standard 2014 free character string; a scalar function either a system, user-defined, or CLR function ; нажмите чтобы прочитать больше NULL can be used as a default.
Must посетить страницу supported in natively compiled stored procedures. When a new row is added to the table, the Database Engine provides a unique, incremental value for the column. Only one identity column can be created per table. Both the seed and increment or neither must be specified. If neither is specified, the default is microsoft sql server standard 2014 free. If this clause is specified for a constraint, the constraint is not enforced when replication agents perform insert, update, or delete operations.
Specifies a column used by the system to automatically record information about row versions in the table and its history table if the table is system versioned and has a history table. For more information, see updateable ledger tables and temporal tables. If you attempt to specify a column that does not meet the above data type or nullability requirements, the system will throw an error. By default, period columns are not hidden. In order to be used, hidden columns must be explicitly included in all queries that directly reference the temporal table.
Specifies to create an index on the table. This can be a clustered index, or a nonclustered index. The index will contain the columns listed, and will sort the data in either ascending or descending order.
Specifies to store the entire table in columnar format with a clustered columnstore index. This always includes all columns in the microsoft sql server standard 2014 free. The data is not sorted in alphabetical or numeric order since the rows are organized to gain columnstore compression benefits. Specifies to create a nonclustered columnstore index адрес страницы the table.
The underlying table can be a rowstore heap or clustered index, or it can be a clustered columnstore index. In all cases, creating a nonclustered columnstore index on a table stores a second copy of the data for the columns in the index. The nonclustered columnstore index is stored and managed as a clustered columnstore index. It is called a nonclustered columnstore index to because the columns can be limited and it exists as a secondary index on a table.
This restriction allows the Database Engine to verify uniqueness of key values within a single partition only. When you partition a non-unique, clustered index, the Database Engine by default adds the partitioning column to the list of clustered index keys, if it is not already specified. When partitioning a non-unique, nonclustered index, the Database Engine adds the partitioning column as a non-key included column of the index, if it is not already specified.
You cannot specify a partitioning scheme on an XML index. If the base table is partitioned, the XML index microsoft sql server standard 2014 free the same microsoft sql server standard 2014 free scheme as the table. For more information about partitioning indexes, Partitioned Tables and Indexes. If no location is specified and the table or view is not partitioned, the index uses the same filegroup as the underlying table or view.
The filegroup must already exist. ON "default" Creates the specified index on the default filegroup. The term default, in this context, is not a keyword. It is an identifier for the default filegroup and must be delimited, as in ON "default" or ON [default]. Otherwise, an error is raised. Using deterministic encryption allows searching using equality comparison, grouping, and joining tables using equality joins based on encrypted values, but can also allow unauthorized users to guess information about encrypted values by examining patterns in the encrypted column.
Joining two tables on columns encrypted deterministically is only possible if both columns are encrypted using the same column encryption key. Deterministic encryption must use a column collation with a binary2 sort order for character columns. Randomized encryption uses a method that encrypts data in a less predictable manner.
Randomized encryption is more secure, but it prevents any computations and indexing on encrypted columns, unless your SQL Server instance supports Always Microsoft sql server standard 2014 free with secure enclaves. Please see Always Encrypted with secure enclaves for details. If you are using Always Encrypted without secure enclavesuse deterministic encryption for columns that will be searched with parameters or grouping parameters, for example a government ID number.
Microsoft sql server standard 2014 free randomized encryption, for data such as a credit card number, which is not grouped with other records or used to join tables, and which is not searched for because you use other columns such as a transaction number to find the row which contains the encrypted column of interest.
If you are using Always Encrypted with secure enclaves, randomized encryption is a recommended encryption type. For more information including feature constraints, see Always Encrypted.
The storage of sparse columns is optimized for null values. For additional restrictions and more information about sparse microsoft sql server standard 2014 free, see Use Sparse Columns. Specifies a dynamic data mask. Four functions are available:. For function parameters, see Dynamic Data Masking. Valid only for varbinary max columns. Collation name can be either a Windows collation name or an SQL collation name.
If not specified, the column is assigned either the collation of the user-defined data type, if the column is of a user-defined data type, or the default collation of the database. Constraint names must be unique within the schema to which the table belongs. For this constraint to execute, the foreign key columns must be nullable. For this constraint to execute, all foreign key columns must have default definitions.
If a column is nullable, and there is no explicit default value set, NULL becomes the implicit default value of the column. For example, in the AdventureWorks database, the ProductVendor table has a referential relationship with the Vendor table. The ProductVendor.
BusinessEntityID foreign key references the Vendor. BusinessEntityID primary key. If any exist, the dependent rows in the ProductVendor table are deleted, and also the row referenced in the Vendor table. For example, in the AdventureWorks database, the ProductVendor table has a referential relationship with the Vendor table: ProductVendor.
BusinessEntity foreign key references the Vendor. If any exist, the dependent microsoft sql server standard 2014 free in the ProductVendor table are updated, and also the row referenced in the Vendor table. CHECK Is a constraint that enforces domain integrity by limiting the possible values that can be entered into a column or columns. Alias data types cannot be part of the expression. The default is ASC. The partition scheme must exist within the database. Doing this makes sure that any CHECK constraints on partitioning columns do not have to check for null values.
User-specified fillfactor values can be from 1 through

Upgrade to Microsoft sql server standard 2014 free Edge to take free vmware for mac key fusion 7 of the latest features, security updates, and technical support. SQL Managed Instance. Specifies a complete database backup. If a list of files and filegroups is specified, only those files and filegroups are backed up. During a microsoft sql server standard 2014 free or differential database backup, SQL Server backs up enough of the transaction log to produce a consistent database when the backup is restored.
Only a log backup can be restored to a specific time or transaction within the backup. Specifies a backup of the transaction log only. The log is backed up from the last successfully executed log backup to the current end of the log. Before you can create the first log backup, you must create a full backup. The log is truncated after all the records within one or more virtual log files become inactive.
If the log is not being truncated after routine log backups, something might be delaying log truncation. For more information, see Factors that can delay log truncation.
Is the database from which the transaction log, partial database, or complete database is backed up. Is the logical name of a file or a variable whose value equates to the logical name of a file that is to be included in the backup. Is the logical name of a filegroup or a variable whose value equates to the logical name of a filegroup that is to be premiere pro cs6 presets free in the backup. Under the simple recovery model, a filegroup backup is allowed only for a read-only filegroup.
Consider using file backups when the database size and performance requirements make a database backup impractical. The NUL device can be used to test the performance microsoft sql server standard 2014 free backups, but should not be used in production environments. The number is unlimited.
Specifies a partial backup. Is the logical name of a read-only filegroup or a variable whose value equates to the logical name of a read-only filegroup that is to be included in the partial backup. For more information about partial backups, see Partial Backups. Indicates that the accompanying set of backup devices is either an unmirrored media set or the first of the mirrors within a mirrored media set for which one or more MIRROR TO clauses are declared.
The logical name must follow the rules for identifiers. For more information and examples, see:. The NUL disk device will discard all information sent to it and should only be used for testing. This is not for production use. Starting with SQL Забыл sony vegas pro 12 keygen 64 bit free отличный The NUL device will discard all input sent to this нажмите сюда, however the backup will still mark all pages as backed up.
For more information, see Backup Devices. Avoid using this feature in new development work, and plan to modify applications that currently use this feature. Specifies a set of up to three secondary backup devices, each of which mirrors the backups devices specified in the TO clause. Посетить страницу order to mirror backups to devices that have different sector sizes, the BLOCKSIZE parameter must be specified, and should be set to the highest sector size amongst all the target devices.
A consistent set of Azure snapshots make up a backup and are recorded in the backup file. With SQL Server Snapshot Backup, after the initial full backup that is required by SQL Server to establish the backup chain, only a single transaction log backup is required to restore a database to the point in time of the transaction log backup. Furthermore, only two transaction log backups are required to restore a database to a point in time between the time of the microsoft sql server standard 2014 free transaction log backups.
A differential backup usually takes up less space than a full backup. Use this option so that all individual log backups читать полностью since the last full backup do not have to be applied. For more information, see Differential Backups. Used to specify encryption for a backup. Encryption is recommended practice to help secure backup files. The list of algorithms you can specify are:.
If you choose to encrypt, you will also have to specify the encryptor using the encryptor options:. No additional encryption happens for the data itself. The backup fails if the database was not encrypted or if the encryption was not completed microsoft sql server standard 2014 free the backup statement was issued. Specifies that the backup is a copy-only посмотреть ещеwhich does not affect the normal sequence of backups.
A copy-only backup is created independently of your regularly scheduled, conventional backups. A copy-only backup does not affect your overall backup and restore procedures for the database.
Copy-only backups should be used in situations in which a backup is taken for a special purpose, such as backing up the log before an online file restore. Typically, a copy-only log backup is used once and then deleted. The differential bitmap is not updated, and differential backups behave as if the copy-only backup does not exist. Subsequent differential backups use the most recent conventional full backup as their base. The copy-only log backup has no effect on the log chain, and other жмите сюда backups behave as if the copy-only backup does not exist.
For more information, see Copy-Only Backups. In SQL Server Enterprise and later versions only, specifies whether backup compression is performed on this backup, overriding the server-level default. At installation, the default behavior is no backup compression. But this default can be changed by setting the backup compression default server configuration option. For information about viewing the current value of this option, see View or Change Server Properties. Specifies the free-form text describing the backup set.
The string can have a maximum of characters. Specifies the name of the backup set. Names can have a maximum of characters. Microsoft sql server standard 2014 free NAME is not specified, it is blank.
Specifies when the backup set for this backup can be overwritten. If neither option is specified, the expiration date is determined by the mediaretention configuration setting. For more information, see Server Configuration Options. These options only prevent SQL Server from overwriting a file. Tapes can be erased using other methods, and disk files can be deleted through the operating system. For information about how to specify datetime values, see Microsoft sql server standard 2014 free and Time Types.
Controls whether the backup operation appends to microsoft sql server standard 2014 free overwrites the existing backup sets on the backup microsoft sql server standard 2014 free. If a media password is defined for the media set, the password microsoft sql server standard 2014 free be supplied.
INIT Specifies that all backup sets should be overwritten, but preserves the media header. If INIT is specified, any existing backup set on that device is overwritten, if conditions permit. By default, BACKUP checks for the following conditions and does not overwrite the backup media if either condition exists:.
Controls whether a backup operation checks the expiration date and time of the backup sets on the media before overwriting them. This is the default behavior. Specifies whether the media header should be written on the microsoft sql server standard 2014 free used for this backup operation, overwriting any existing media header and backup sets.
FORMAT causes the backup operation to write a new media header on all media volumes used for the backup operation. The existing contents of the volume become invalid, because any existing media header and backup sets are overwritten. Formatting any volume of a media set renders the entire media set unusable.
For example, if you initialize a single tape belonging microsoft sql server standard 2014 free an existing striped media set, the entire media set is rendered useless.
Specifies the media name for the entire backup media set. If it is not specified, or if the SKIP option is specified, there is no verification check of the media name. Specifies the physical block size, in bytes. The supported sizes are,,and 64 KB bytes. The default is for tape devices and otherwise. Typically, this option is unnecessary because BACKUP automatically selects a block size that is appropriate to the device.
Explicitly stating a block size overrides the automatic selection of block size. You can specify any positive integer; however, large numbers of buffers might cause "out of memory" errors because of inadequate virtual address space in the Sqlservr. Specifies the largest перейти of transfer in bytes to be used between SQL Server and the backup media.
The possible values are multiples of bytes 64 KB ranging up to bytes 4 MB. For more information microsoft sql server standard 2014 free using backup compression with TDE encrypted databases, see the Remarks section. These options allow you to determine whether backup checksums are enabled for the backup operation and whether the operation stops on encountering an error. CHECKSUM Specifies that the backup operation verifies each page for checksum and torn page, if enabled and available, and generate a checksum for the entire backup.
Beginning with SQL Serverhas no effect. This option is accepted by the version for compatibility with previous versions of SQL Server. Displays a message each time another percentage completes, and is used to gauge progress. If percentage is omitted, SQL Server displays a message after each 10 percent is completed. The STATS option reports the percentage complete microsoft sql server standard 2014 free of the threshold for reporting the next interval.
